Graco 15B189 Housing Adapter – Product Details & Compatibility
Compatible Machines
The Graco 15B189 Housing Adapter is designed for use within a range of Graco spray‑gun, fluid delivery, and control‑board assemblies where precise housing alignment and adapter interfacing are required.
- Graco airless and air‑assisted paint spray guns with modular front‑end assemblies
- Graco electric and pneumatic sprayers which require a housing adapter to fit interchangeably with nozzles or spray discs
- Graco industrial fluid delivery systems where control modules or gun heads use adaptor housings rather than full replacement components
Product Overview
The Graco 15B189 Housing Adapter serves as a precision interface component in Graco spraying equipment, allowing seamless integration of nozzle assemblies, spray‑disc modules, or gun heads into existing environments. It is manufactured to original‑equipment manufacturer (OEM) standards, ensuring correct alignment, mechanical fit, and fluid‑path compatibility. This adapter supports maintenance or retrofit operations by enabling users to upgrade or replace housing components without replacing larger assemblies, thereby reducing downtime and cost.
Key Features
- OEM Graco housing adapter for secure, reliable fit in spray‑gun or fluid‑system assemblies
- Provides a coupling interface between gun head/housing and nozzle or front‑end module
- Durable construction suitable for industrial spraying environments with exposure to solvents, coatings, or chemical agents
- Compact profile that allows retrofit into existing Graco components without major redesign or modification

Usage Notes
- Ensure the equipment is powered down and pressure relieved before removing or installing the adapter.
- Use the exact Graco part 15B189 to maintain OEM fit and performance; substitution may result in misalignment, leakage, or reduced component life.
- Inspect mating surfaces and seals for wear or damage before installation to ensure optimal sealing and function.
- After installation, perform a leak‑check and verify correct spray pattern or fluid flow to confirm proper integration.
Frequently Asked Questions
It serves as a mechanical interface component, allowing a nozzle or spray‑module assembly to be fitted into a Graco gun or housing assembly with proper alignment and sealing.
While another adapter may physically fit, using the OEM Graco 15B189 ensures correct dimensional tolerances, alignment with mating components, and reliability under industrial spray conditions.
Replace the adapter if the housing shows signs of damage such as cracks, visible wear at the seating surface, misalignment with the nozzle assembly, or if you experience leakage or poor spray performance after installation.
